How to remove the IStreamSearch browser hijacker?

IStreamSearch browser hijacker removal instructions

What is IStreamSearch?

IStreamSearch is a piece of rogue software, designed to make modifications to browser settings in order to promote istreamsearch.com - a fake search engine. Due to this, IStreamSearch is classified as a browser hijacker. Furthermore, this browser hijacker also has data tracking abilities, which are used to spy on users' browsing activity. Due to the questionable methods used to distribute IStreamSearch, it is deemed to be a PUA (Potentially Unwanted Application).

Popular browsers with large user bases are common targets of browser hijackers. They reassign browsers' homepage, default search engine and new tab/window URLs - to the addresses of fake web searchers. IStreamSearch also makes these alterations to browsers to promote istreamsearch.com. To elaborate how these modifications affect browsing, with IStreamSearch installed: every new browser tab/window opened and search query typed into the URL bar - redirect to istreamsearch.com. Illegitimate search engines are seldom capable of providing search results, so they redirect to (or cause redirection chains ending with) Google, Yahoo, Bing and other genuine ones. The web searcher promoted by IStreamSearch - istreamsearch.com - is not an exception to this, it redirects to the Yahoo (search.yahoo.com) search engine. Browser hijackers can restrict/deny access to the browsers' settings and/or undo any permitted changes made. Therefore, recovering an affected browser is impossible without removing the browser hijacker. As mentioned in the introduction, IStreamSearch can track data. It can record browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). This sensitive information is then shared with and/or sold to third parties (potentially, cyber criminals). In summary, presence of data-tracking software on devices can lead to serious privacy issues, financial losses and even identity theft. To ensure browser/system integrity and user safety, all suspicious applications and browser extensions/plug-ins must be eliminated immediately upon detection.

MovieSearches, ConverterSearchNow, Jolly Web are a couple examples of browser hijackers. They appear legitimate and offer a wide variety of "handy" functionalities. However, the promised features are seldom operational. In fact, this is true of practically all PUAs. The only goal of unwanted software is to generate revenue for the developers; to users - they have no real value and can cause severe problems. PUAs are designed to hijack browsers, cause redirects, run intrusive advertisement campaigns and collect private data.

How did IStreamSearch install on my computer?

Select PUAs (e.g. IStreamSearch) have "official" download pages. These applications can also be downloaded/installed together with other programs. "Bundling" is the term used to define this false marketing technique of packing regular software with unwanted or malicious additions. Rushed download/installation processes (e.g. ignored terms, skipped steps and sections, etc.) - increase the risk of unintentionally allowing bundled content into the system. Upon being clicked, intrusive adverts can execute scripts to download/install PUAs without user permission.

How to avoid installation of potentially unwanted applications?

It is recommended to research software before download/installation and/or purchase. It is crucial to only download from official and verified sources. Since untrustworthy channels, like: unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - often offer deceptive and/or bundled content. When downloading/installing, it is important to read terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out from supplementary apps, tools, features, etc. Intrusive advertisements typically appear ordinary and harmless, however they redirect to various questionable webpages (e.g. gambling, pornography, adult-dating, and so on). In case of encounters with ads and/or redirects of this kind, the system must be inspected and all suspect applications and browser extensions/plug-ins - removed from it without delay. If your computer is already infected with IStreamSearch, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
